ANTISKID DEVICE FOR AUTOMOBILE TIRES AND THE LIKE Filed 001;. 4, 1950 INVENTOR.

margin of the disc.
A principal object of the invention is to provide'a device effective for the purpose indicated, which can be speedily applied to the'tire, which will not tend to loosen, creep or become detached during use, and which is quickly removed.
My device comprises, in addition to one or more road engaging elements, as metal chains, a substantially U-shaped, felly-straddling band by means of which the device is fastened about the tire. One leg of this band is detachably connectable, as in hasp and staple fashion, to a cross piece which is linked to the road-engaging element or elements atone end thereof, the cross piece, in the preferred construction, being formed to provide a guideway for the leg of the band. To avoid the possibility of accidental disengagement of the cross piece and band in use of the device, a'locking member'is provided having a portion formed to be looped about the leg of the band. and portions adapted to be held tightly against the cross piece. In the preferred construction the means for so holding these latter portions against the cross piece takes the form of another cross piece which is linked to the first cross piece through resilient means and which serves as a handle in the application of the'device to the tire.
' I shall describe my invention in its preferred embodiment with the aid of the accompanying drawings, in which: I
- Fig. 1 is a section on the line II of Fig. 2;
Fig. 2 is an elevation illustrating the device as applied to a tire;
Figs. 3 and 4 are plan views taken on the lines 3-3 and 4-4 of Fig. 2;
Fig. 5 is an elevation of the part shown in plan inFig. 4;
Fig. 6 is an enlarged perspective view of the band member; and
Fig. '7 is an enlarged perspective view showing the inner face of the cross piece appearing in plan in Fig. 3.
Referring first particularly to Figs. 1 and 2, the tire I0 is shown as mounted on a disc wheel I I having spaced marginal slots I2. Rim I4 is integral with the wheel.
Extending across the tread of the tire are chains I5, connected at their ends to cross pieces 6 Claims. (Cl. 152-237) I6 and I'Lthese being suitably apertured, to receive the terminal links of the chains. If desired, cross piece I'I, shown as spot-welded to band or strap I8, may be deta'chablyconnected thereto. This band passes through the aperture I2, straddles the felly or rim I4 and partially encircles the tire. It may be conveniently formed by stamping from sheet metal. While the metal must be capable of taking a set, it should possess a substantial measure of resiliency.
Downturned flanges 20 (Fig. 7) spaced equidistant from the ends of cross piece I6 provide a guideway for the band I8, the width of the guideway approximating that of the band. The purpose of the guideway is to prevent lateral or making movement of the band relative to the cross piece. r v
A hook element 22, shown as integral with the cross piece I6 and positioned mediate the flanges 20, is receivable in any one of the apertures I9 in the band I8. The peculiar shape of this hook element facilitates its insertion in the selectedaperture.
Cross piece 23- serves as a handle in the insertion of the hook 22 in an aperture providing a tight fit. This member is connected to cross piece I6 by springs 24 or other resilient means, and itself comprises a hook 25 receivable in any of the apertures I9 in the band I8.
A most important part of the device is the wire locking element 26, which operates to prevent accidental unseatingof the hook 22 with resultant loosening of the device. This element will be noted as distorted in its area behind the band I8 (Figs. 2 and 3), the distortion providing a portion 21 seating in one of the apertures I9 above the cross piece I6. The legs 28, which overlie and bear on the cross piece, and which are tensioned so as to resist being spread apart, snap into complementary recesses 29 in the cross piece 23, access to these recesses being had through notches 30 which communicate with wider notches 3| disposed at right angles thereto. The slight downward bowing of the legs 28 incident to the seating of the legs in the recesses so tensions thelegs as to preclude the possibility of the legs slipping out of the recesses. v,
To apply the device, the apertured leg of the band I8 is thrown over the tread of the tire (from the right in Fig.1) and the end of the band passed through the slot I2. After such leg of the band has been pulled upward to properly position the chains across the tread, cross piece 23 is pulled downward until the hook 22 of the cross piece I6 is adjacent the proper aperture, the
tool for use in removing the device from the tire.-
In this connection, the legs 28, after the lock has been removed, are re-inserted in the notches! or slots from below the cross piece'23 (Fig. 2) and the lock employed as a lever by, lifting up to unseat the hook 25. .The. unseating of this hook and the resultant freeing of the cross My invention is not to be restricted to the precise details of construction shown in the drawings, since various changes and modifications obviouslymay be made without departing from the scope ofthe invention or sacrificing. the advantages derived from its use.
